Nearly seven months on detectives are yet to eliminate Rees, who identifies as male but dresses in women’s clothing, from the investigation.

Rees, from Penzance in Cornwall, is terrified he will be arrested on suspicion of the violent killing.

He said: ‘I didn’t want to go to the police because it might look like I’m involved. But I got fed up with Linda showing me the murder, so I took the information to the police. What Linda was showing me was quite graphic and prolonged.

‘I was quite shocked when I saw these two cops outside in suits and took a DNA sample – they didn’t say why. It must be because the information was so accurate it gave them cause to think I was the murderer.’

The clairvoyant added: ‘It was six months ago and they have just left me hanging. I don’t know if they are still investigating or treating me as a suspect.’

Married Linda, 41, was attacked while walking her lurcher dog Jay near her home in the quiet hamlet of Ruan Highlanes, Cornwall, on October 20, 1998.

She was stabbed in the neck, chest and back and the killer has never been found, despite police interviewing every local man between the ages of 14 and 70.

But Tristan, who claims to have been clairvoyant since he was a child, said just six months after the murder he was visited by the spirit of Mrs Bryant.

He said: ‘The visions just came to me at any time. It was almost like looking at a film but I’m right there next to her and the killer. It was always the same pictures of her walking down the lane and the killer following her and then he walks back to a van he’s got.’

Tristan claims the ‘killer’ has greying ginger hair, a wrinkled face and is quite slim and wearing a blue boiler suit and boots and driving a large white van.

He added: ‘His boiler suit and boots were covered with blood, but you couldn’t tell it was blood because it was on dark material.’

Tristan said he was plagued by the images for 15 years before he approached Devon and Cornwall Police in 2013 with his own drawings of the suspect and detailed descriptions.

He left the paperwork at a police station – and the visions stopped – and heard nothing until two years later when two plain-clothed officers visited him last June.

Despite apparently promising to contact him with the results in the coming weeks, he claims police haven’t been in touch, leaving him worried he is considered a suspect.

‘They didn’t tell me what the DNA was for,’ Rees said. ‘I’d like to know if the information was useful.’

Devon and Cornwall Police would not confirm if Tristan was still being considered as part of the investigation, but said they were grateful for any information.

A spokesman said: ‘Police met with Tristan Rees in June 2015 after he contacted us stating that he had been receiving premonitions about Linda Bryant’s murder. He provided information to us via a brief statement and his DNA was taken with his consent as a routine procedure.

‘The police are always grateful for any information regarding this, or any other case.’
